versioning:
  scheme: semver-in-info-version
  current: 1.34.1
  note: >-
    The engine version is published in the OpenAPI info.version and echoed by GET /ping. It is NOT in the
    URL path and NOT negotiated by header — there is one unversioned live contract at
    https://imgauth.spaziogenesi.org, so a version bump is visible only after the fact via the changelog.

deprecation:
  policy_url: null
  sunset_header: false
  note: >-
    No published deprecation policy and no RFC 8594 Sunset/Deprecation header support. Nothing in the
    contract is marked deprecated. The one breaking change to date (1.15, 2026-07-01, hashing moved to the
    client) was announced in the changelog only. This is a real gap for a service whose value proposition
    is long-horizon proof of existence.
sla:
  url: null
  uptime_target: null
  note: >-
    No numeric uptime commitment is published. What IS published, per tier, is certificate RETENTION —
    the durability guarantee that matters for an attestation service.
  retention:
    base: at least 6 months
    developer: at least 12 months
    professional: at least 5 years
    convention: at least 5 years
    proof_of_existence: >-
      never expires — the Bitcoin/OpenTimestamps anchor and the RFC 3161 mark remain verifiable
      independently of the service

  history: https://imgauth.spaziogenesi.org/api/status-history
  health_log: https://imgauth.spaziogenesi.org/api/health-log
  note: >-
    Unusually strong for a provider this size: the status page is backed by three PUBLIC, CORS-open,
    machine-readable endpoints — live component state (worker/archive/signer/anchor), a 90-day daily
    rollup with 30-minute banding, and a per-day fine-grained health-event log.
